(Cl. I56-42) 7 Claims.

'M5/:invention relates to cottonpicking machines of the kind disclosedin yUnited States Patents No. Re. 19,411 issued January l, 1935, No.1,894,198 issued January l0, 1933, No. 2,058,513 issuedOctober 27, 1936,No. 2,023,491 issued December 10, 1935, No. 2,058,514 issued October 27,1936, No. 2,085,0461issued June 29, l1937, and No. 2,162,750 issued June2i), 1939.

My present .invention seeks to provide an improved means forrougheningrthe steel wire spindles of the cotton picking machine.

Other 4objects will in part be obvious and in part be pointed outhereinafter,

To the attainmentiof the aforesaid objects and ends, the invention alsoresides in the novel details of construction, combination and arrange--ment of parts, all of which will be first -fuily described in thefollowing detailed description, and then be particularly pointed out inthe appended claims, reference being had to the accompanying drawings,in which:

Fig. 1 is a top plan view of a portion fof a cotton picking machineembodying my invention, parts being broken away and parts beingshownin-section Fig. 2 is an enlarged detail section on the line 2 2 of Fig.1.

Fig. 3 is an enlarged detail horizontal section on the line `3 3 of thetubular post in Fig. '2 and a pair of springy rods carried thereby.

Fig. 4 `is a detail perspective on an enlarged scale View of oneof theshoes.

vReferring now to .the accompanying drawings, in which like numerals andletters of reference indicate like parts in all ythe figures, the `mainframe of the machine includes angle irons i, la, I b, cross bars Ic, Idand longitudinal bar le, 2 the drive shaft, 3 the driven shaft, 4 theconveyor chains, 5 the spindle carrying slats and 5a the brackets whichconnect the slats to the chains. The main .frame is of knownconstruction and per se is not a part of my present invention.

The spindle roughener is best `illustrated in Figs. 2, 3 and 4. A shaft'carries a set of spaced rigid discs 1 to the under faces of which aresecured abrasive rings 8. Thediscs 1 are spaced apart by suitablespacers 9 and secured by arnut I'Il threaded on the shaft so that theshaft and the discs With their abrasive rings comprise a unitarystructure. The shaft lis bored at its lower end to set on a pin I!carried by a bracket I2. The upper end of the shaft carries a swivelhead I3 having trunnions I4 to rest in the bifurcated end of an arm I5pivotally mounted at I6. An adjustable stop I1 limits the distance the 2arm may rise, and hence limits the Ilift of ythe stack of abrasive unit.This unit is-res-ili'ently suspended by .means Yor a .lever .'18fulcrumed at I19and held by a spring pressed'bolt 2120. 'Thellever i8has its freefend inserted in an eye for IloopfLI on Vthe -arm I5.

22 is a pipe, carried by fthe fir-fame 4of the machine. On the pipe 212-is .pivoted va rocker 23:one end of ,which-presses on .the swivel headI3 vWhile the other end is pivoted toan. eyeboltfzkthreaded into theupper end of a tubular'post 125 on 'fthe lower end of which post is afoot 21 whichmay ride up and down in a xed guide :(26. Thefpost 25carries suitably spaced ,pairs of rods 1:28 having ends 29 on Which'arecarried shoes .lf3-0 lthat project between the adjacent abrasivedisc'units'. When in non-operating position the shoes rest on top of the.metal disc elements 1 leaving both the shoes 30 and the .abrasiveelement/8 outoi contact with the spindles 32. 'The shoes ..30 havetapered front ends 3l :to cause the :spindles to ride up over the arms.3.0 at Val1 times. At the ends adjacent the .post 25 guards 33 aresecured on the shoes 30 to prevent cotton from :being thrown over thoselends and accumulatingvonathe arms 28.

An operating arm `34 is secured to-the'pipefzz, to which the rocker 23is also secured for the purpose of rocking the rocker 23 and therebylowering the abrasive units shaft 6 and raising the post 25 inconsequence of which fthe vspindles 32 will be held in contact with theabrasive; The arm 34 is operated by a piston 35 in a cylinder36, thepiston rod 31 being pivoted to the arm 34. Suitable operating iiuid isadmitted into the cylinder 36 from a suitable operator-comtrolled source(not shown-but wel1=known^l via a pipe 38.

`The shaft '6 is `rotated-step-by-step at suitable intervals by means ofa vpawl-carrying-lever135 pivoted on shaft 6 and having a pawl-40 ltoengage a ratchet 4I on the upper 'face of the top disc 1. The lever 39has a pin-42 which lies'in an elongated slot 43EL in a connecting rodL43 Athat is pivoted to the yoperating lever 44 (see Fig. '1). The lever44 is supported in any suitable wel] known way, on a pivot 44a.

A rock shaft 45, mounted on the frame of the machine in any suitableknown manner,` carries' ngers 4B that project between the elements gofthe abradingunit to throw out any cotton 'that vided an endless conveyorwith cotton pickingl spindle-carrying slats: the improvement whichincludes a spindle roughening device between the elements of which thespindles are drawn by thev endless conveyor; said device comprising avershaft; means for mounting said shaft for longiltudinal movement; apost, shoes carried by said post; means for mounting said post forlongitudinal movement parallel to that of said shaft; op

tical set of abrasive-carrying discs spaced apart on a shaft, acorresponding set of spindle engaging shoes on a post, the shoesprojecting in between pairs of said discs and spaced therefrom, thespindles being carried by the conveyor between the abrasive-carryingdiscs and the shoes, and means for moving said abrasive-carrying discsand said shoes in opposite directions along the axis of said shaft tobring the abrasive surfaces and said shoes into operative engagementwith said spindles, said last named means comprising yieldable means forsuspending said abrasive-disc-carrying shaft, means for suspending saidshoe-,carrying post, a rock shaft with a rocker engaging saidabrasive-disc-carrying shaft and connected to said post by virtue ofwhich as said rocker is moved to depress the abrasive-disc-carryingshaft it willsimultaneously lift said post for purposes described.

2. A spindle roughening device for roughening cotton picking spindlescarried through the device: said device comprising a shaft carrying aplurality of abrasive elements spaced apart on the shaft; means formounting said shaft for longitudinal movement; a post, shoes carried bysaid post; means for mounting said post for longitudinal movementparallel to that of said shaft; operator-controlled means operativelyconnected to said post and shaft for simultaneously moving said post andsaidshaft in opposite directions to press the spindles between saidabrasive elements and said shoes.

3. A spindle roughening device for roughening cotton picking spindlescarried through the de vice: said device comprising a shaft carrying aplurality of abrasive elements spaced apart on the shaft: means formounting said shaft for longitudinal movement; a post, shoes carried bysaid post; means for mounting said post for longitudinal movementparallel to that of said shaft; operator-controlled means operativelyconnected to said post and shaft for simultaneously moving said post andsaid shaft in opposite directions to press the spindles between saidabrasive elements and said shoes; and means to impart intermittentrotation to said shaft.

4. A spindle roughening device for roughening cotton picking spindlescarried through the device: Said device comprising a shaft carrying aplurality of abrasive elements spaced apart on the shaft; means formounting said shaft for longitudinal movement; a post, shoes carried bysaid post; means for mounting said post for longitudinal movementparallel to that of said shaft; op-
